I'm running Strawberry on XP and out of the blue, with no interactions, I started getting this error on all my
and backtik calls.
Re-installed Strawberry and everything. So the issue ended up being a duplicate path setting in my windows environment variables.
There's a 'system' path and a per user path. Basically the fix is (in XP) right click on my computer -> properties -> Advanced tab -> environment variables.
Copy the system PATH variable in the bottom pane to the user one in the top pane, or append it to the one in the top pane. That was my solution and had nothing to do with directory path. Though yours may be a combination of both as the path isn't enclosed in quotes. escape some quotes inside the variable and do the PATH variable thing.
